PLEASE HELP!!! I am stuck on this step...I dont know where to go from here...I am stuck after casting on my first row

What do I do now that I have my first row casted on?

And I did not use the long tailed version I used the single version because it was easier for me and I couldnt get the knot tied on the long tailed version, somebody please please help me, I need to know where to go from here, which step do I take?

On the Tips page, there's a video Demo of a Small Project. That showls casting on (which is not the first row, it's just the cast on), then knitting a few rows. That should help. You don't need to make a knot to start your cast on, btw, you can loop it around the needle.
